18 x 18 USB / AVB Audio Interface with DSP Mixing, Wi-Fi Control and Audio Networking
The latest in MOTU's popular, award-winning UltraLite interface series, the UltraLite AVB is an 18-input, 18-output audio interface with DSP mixing, wi-fi control, AVB audio networking and best-in-class analog audio quality for on-the-go mobile audio recording.

36 simultaneous audio channels

The most I/O ever offered in the UltraLite series
You get 2 mic inputs, 2 guitar inputs, 6 line inputs, 8 line outputs, headphone out and 8-channel optical I/O for a total of 18 inputs and 18 outputs, simultaneously. The optical ports also support stereo TOSLink (optical S/PDIF).

Best-in-class analog audio quality

Performance suitable for the most demanding situations
The UltraLite AVB sets a new standard for analog audio performance in a mobile audio interface. The eight balanced analog outputs deliver a stunning 117 dB dynamic range. This level of measured performance had previously only been available in audio interfaces that cost thousands of dollars.

Universal connectivity

Class compliant USB 2.0 plus audio over Ethernet
The UltraLite AVB connects to your computer with audio class compliant hi-speed USB 2.0 (compatible with USB 3.0 and iOS) for across-the-board compatibility now and in the future. Alternately, if you have a Mac running OS X Yosemite (10.10) or later, you can use a standard Ethernet cable for operation as an audio interface. Either way, the UltraLite AVB is compatible with all audio software.

DSP-powered mixing

Console-style mixing with 48 channels and 12 busses
The mixer in the UltraLite AVB is a complete departure from earlier models. In fact, it's identical to the mixer found in MOTU's flagship 1248 and 16A interfaces. If you know your way around a large-format mixing console, you'll feel right at home. If you've ever wished to mix on a large console, the driver's seat is now yours.

Modeled analog EQ and compression

Vintage processing with 32-bit float precision
British analog mixing consoles are renowned for their musical EQ profiles. The UltraLite AVB meticulously models these classic EQs to give you the very same, magical EQ response found on these coveted desks. Each input channel also provides a classic compressor with peak/RMS operation.

Groups and the Main Mix bus are equipped with MOTU's Leveler™, an accurate model of the legendary Teletronix™ LA-2A™ optical leveling amplifier, known for its highly sought-after Automatic Gain Control (AGC) characteristics.

Web app control from any device

Control everything from your laptop, tablet and smartphone
The software that you use to control the UltraLite AVB doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the UltraLite AVB on-board DSP, mixing, device settings, and network audio routing from your favorite web browser on a laptop, tablet or smartphone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linux, iOS, Android - as long as it shares the same network.

Touch Console

The art of the mix on your touchscreen
Designed specifically for touchscreen operation, Touch Console™ delivers a whole new mixing experience. Access Touch Console from your tablet or smartphone to effortlessly control the powerful 48-channel mixer and effects in the UltraLite AVB. With large targets for your fingers, multi-touch operation and intuitive design, you can tap, swipe and pinch your way to a perfect mix, every time.

Stand-alone mixing with wireless control

Control everything from your iPad or iPhone
Connect an Apple Airport^™ or other Wi-Fi router directly to the UltraLite with a standard Ethernet cable and control the UltraLite AVB's powerful mixing and DSP effects from your smartphone or tablet, without a computer. Great for live sound mixing!
